Increasing physical activity and limiting television may lead to reduction in type 2 diabetes

"Researchers from Boston University's Slone Epidemiology Center have found that reducing time spent watching television and increasing time spent walking briskly or engaged in vigorous physical activity may reduce the incidence of type 2 diabetes in African-American women. These findings appear on-line in the American Journal of Epidemiology. Type 2 diabetes has reached epidemic proportions in the U.S. and affects an estimated 20.6 million people. African-American women make up a significant percentage of that population. Although previous studies support a role for physical activity in preventing type 2 diabetes, there has been little attention focused on the impact of this factor in the high-risk population of African-American women" - EurekAlert

'Body clock gene' diabetes clue

"The workings of our internal body clock appear to be directly connected to our risk of diabetes, researchers claim. International research published in the journal Nature Genetics found faults in a key 'clock gene' were linked to blood sugar levels and type II diabetes. Some scientists already believe that our circadian rhythms (body clock) have a role to play in the condition, which affects millions worldwide. But one expert said more evidence was needed, before a link was proved" - BBC
